I also believe subspace is different for every sub. Its all those dreams and fantasys that you had as you grew up. Wondering if they would ever become reality. And your unconscious holds those memorys and when you actually experience them your whole body just goes into this bliss....everything around you vanishes. Its like your lifted to a place you have never been before, but you know you want to go there again, again. I think your whole body lets go, there is no time, no sense of being. My Masters voice starts and ends it..he controls how long i stay there. For me, its not knowing when he will take me there,,,,its not the anticipation of knowing that starts the journey...but the immediate rush when it does. I am, so far, not into intense pain, i think my Master gets inside my mind, and his power grows...He is my Master, and I will always be his submissive...
